grey and black - 3/22/15

I didn't realize quite how bad I've been about my "daily" photo until I checked the date on the last outfit photo I did, which was over a week ago!  Anyway, here is last Sunday's outfit, which is one of my staple sweaters.  It's getting a bit pilly lately though, and I've never had good luck with sweater shavers.  Any recommendations?  How do you take care of sweaters?
